3 Claims. 1

This invention relates to a double acting liquid dispensing fixture. .More particularly, it comprises a single fixture, having hot and cold water supplies, the outlet therefor being connected through to a pair of disk valves adapted to supply in selected proportions hot and cold water to a discharge nozzle or outlet, such as a swiveling delivery spout.

The principal object of said invention is to provide a fixture of this character having a double acting valve adapted to deliver hot and cold water in predetermined proportions to a spout.

Another object of'the invention is to provide a valve structure with a central mixing chamber associated with a delivery spout and having valve members at each side thereof adapted to admit hot and cold water to such mixing chamber in predetermined proportions.

Another object of the invention is to provide a mixing chamber of simple construction, wherein the hot and cold water supplies are controlled by a pair of disk valves mounted on a common valve stem, operated by a single handle and adapted to supply hot and cold water to a swiveling spout in proportional amounts according to the angular position of such handle and valves.

Another object of the invention is to provide a sink fixture made of few parts and readily assembled and installed, and adapted to deliver proportional amounts of hot and cold water selectively to a swiveling spout.

Other and further objects of the invention will appear in the course of the following description.

To the accomplishment of the foregoing and related ends, said. invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawings and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but several of various forms in which the principle of the invention may be used.

In said annexed drawings:

Fig. l is a top plan view of a fixture embodying the principles of the invention;

Fig. 2 is a front elevation of the structure shown in Fig. 1; r

Fig. 3 is a perspective view, partly in section, showing the fixture and the valve disks and associated parts in separated expanded relation;

Fig. 4 is a central vertical sectional view of the central body portion of the fixture; and

Fig. 5 is a central horizontal sectional view of the mixing chamber showing the water supply chambersand the valve disks. 7

1 I02 and the flow chamber 8.

As shown in Figs. 1 and 2, the fixture comprises a body portion I0 having therein a central mixing chamber I (later referred to), connected.

through a coupling Illa with a cold water supply lineZ at one side and through a coupling IOb with a hot water supply line 3 at the other side, as later set forth, and having a swiveling spout 4 mounted on the top surface of the body portion I6 and a valve control handle 5 projecting from the forward face of the body portion Ill.

The body portion I0 consists of an annular'wall I0 the inner walls of which adjacent the side edges thereof are provided with screw threads Ill" engaged by the screw threaded side walls of caps IE to provide flow chambers I, 8, as later set forth. The upper side of the wall I0 is extended to provide an outlet nipple [0x to which.

axially of the annular wall I0 and side walls Id.

The annulus lc provides a bearing through which the stem 50, of the valve rotatably extends. The transverse walls la, lb, are integrally connected at their lower portions I (1., lb, to the adjacent portion of the annular wall I0, whereas upper portions Ia", lb, of the walls Ia, lb, extend laterally and are integrally connected with the annular wall I0. at opposite sides of the nipple Iilx, thereby providing an outlet passage leading from the mixing chamber I directly to the nipple I031. Intermediate the wall portions Ia-lb' and wall. portions Ia"-I b", the mixing chamber I are provided with the outer side walls I d integrallyrelated to the walls la, la, above and below the. annulus lc. As shown in Fig. 5, one side wall Id is extended laterally and integrally connected to the annular wall I0 along the inner side of the nipple I02, to provide a flow connections."

between the nipple I02 and flow chamber I, whereas the other side wall Id is extended laterally and integrally connected to the annular wall I0 along theinner side of the nipple I02 to provide a flow connection :12 between the nipple The transverse wall Ib is formed with a pair of diametrically related ports II, IIa, their axes preferably being disposed at right angles to the axes of the nipples I02, I02, whereas the wall la is formed with two pairs of diametrically related ports 12-420 I2'--l2a, the ports [2, l2, and ports Ila, lZa', being disposed on radii of the axis of the stem So at opposite sides of and angularly spaced from the ports-ll, Ha, respectively. By preference, the ports 12, Ha, are disposed below and above the ports H, I la, respectively, and their axes are spaced from the axes thereof at an angle of 35 degrees, respectively, whereas the ports l2, Ha, are disposed above and below the ports ll, Ha, respectively, and their axes are spaced from the axes thereof at an angle of 30 degrees.

[3, [6, indicate valve disks, suitably keyed to the valve stem 5a in face-to-face relation to the opposite outer sides of the walls la, lb, respectively, and adapted to be rotatively operated by the valve stem 5a. The disk [3 is formed with four uniformly spaced apertures 9, each adapted to be moved into partial or full registry with one of the apertures l2l2a, l2'-i2a', formed in the wall la, whereas the disk I6 is formed with two diametrically related apertures ll, each adapted to be moved into partial or full registry with one of the ports ll, Ha. A compression spring M is interposed between the disk l3 and the adjacent cap 15 and a compression spring I8 is interposed between the disk It and the adjacent cap IS. The springs M, It, serve to normally apply pressure against the disks l3, 16,

when the parts are assembled in operative relation to provide sealing engagement thereof with the walls la, lb, respectively. The opposite ends of each compression spring are seated around collars provided on the opposed faces of each valve disk and cap l5.

As will be observed, the cold water flows through nipple Hi2, passage :1: to flow chamber 1 for supply through apertures 9 and ports l2--l2a, l2--l2a', into the mixing chamber I and hot water flows through nipple I02, passage 3: to flow chamber 8 for supply through apertures l1 and ports H, lla,"into the mixing chamber l, whereby selected proportions of cold and hot water may be supplied for mixing in the chamber I for discharge from the spout 4.

The swivelingspout 4 has a downwardly turned outer end portion 2| for discharging the liquid supplied .to the spout. The downwardly extending inner end 4a of the spout 4 is screw threaded to engage the screw threaded portion on the inner wall of the nipple llla: provided at the top of the body portion 10 and communicating with the central mixing chamber l, as heretofore described. A compressible sealing member 23 is adapted to be seated between the downwardly turned end 411. of the spout and the nipple 10m to prevent leakage of liquid therefrom as the spout is turned to various positions of adjustment. It will be observed that the walls la, lb, serve as valve seats and the disks l3, l6, serve as valve elements to control the flow of hot and/ or cold water to the mixing chamber. In this arrangement, the use of washers of any kind and stufling boxes are eliminated and as the disks l3, 16, are in face-to-face engagement with the walls la, lb, under pressure, the rotative movement of the disks provides a grinding action between their engaged faces to insure efiicient control of the water to the spout 4 and prevent leakage when flow of water to the spout is entirely cut ofi.

It will be noted that the valve disks l3 and 16 have central apertures 24, 25, respectively, which are grooved so as to interlockingly engage upon fluted or ribbed portions 26, 21, respectively,

formed on a valve shaft or stem 5a, which is rotatably supported in the annulus lc for movement by the handle 5 to various positions of angular adjustment. The handle 5, as shown more particularly in Fig. 2, is provided at its outer end with a ball 30 and with a conical pointer 3| at its inner end revoluble relative to the outer face of the adjacent cap 15, so that by means of suitable graduations (not shown) on the latter the adjustment of the valve disks l3 and IE will be indicated.

The fixture may be provided in an elevated position with a rectangular soap dish 34, supported upon a suitable upstanding arm or bracket 35, connected with the rearward portion of the body member Hi.

It will be noted that the ports or apertures 11 on the hot water side of the mixing chamber are larger than the cold water ports 9, and are positioned at an angle of 45 degrees to the position of the apertures or ports 9 on the cold water side of the mixing chamber, and this angular diiierence and diiference in size permits the valve disks l3 and 16 to be set at suitable angles to each other so as to provide for an increased flow of hot water as the handle 5 is moved in a clockwise direction and for an increase in the cold water supply as the handle 5 is moved in a counter-clockwise direction. Movement of the handle 5 to the position a: (Fig. 2) will completely shut oif the water from the hot and cold water supplies, and the turning of the valve control handle 5 to a horizontal position x in alignment with the cold water supply line will cause the entire water supply to be cold water and the turning of the handle downwardly to an angle of 45 degrees, as indicated at x", will cause the water supply to be wholly from the hot water supply line. Any intermediate positions will provide proportionate mixtures of hot and cold water, so that any desired temperature of the water delivered through the spout may be had by setting the valve control handle at the appropriate angle for the temperature required. To set a shut-off limit to the movement of the handle, an upstanding lug 6a: on the handle will contact with a stop lug 36 on the body. A sealing device 33 may be used on the stem 5a to prevent leakage near the handle 5.

Other modes of applying the principle of my invention may be employed instead of those explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.
